Nouveau fails to drive the LVDS screen of an Acer Extensa 5635G laptop. This seems to be due to the laptop having a corrupt EDID.
The latest nvidia beta drivers seem to have a quirk for it, and there's a corrected EDID available here: http://www.nvnews.net/vbulletin/showpost.php?p=2167144&postcount=13

IANAXD (I Am Not A X Developer), but these patches *might* fix this:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=7064fef56369c9e2c6e35ff6d6b4b63d42a859ce (upstream since 2.6.32)
http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=commit;h=44fef22416886a04d432043f741a6faf2c6ffefd (pending upstream, probably will go to 2.6.35)
Thanks for that pointer; the second patch does fix it for the reporter.
